Neil Schemenauer d87affece4 Improve some docstrings in the 'warnings' module. 2009-10-23 19:58:17 +00:00
Brett Cannon 6c4cff0f32 Require implementations for warnings.showwarning() support the 'line' argument.
Was a DeprecationWarning for not supporting it since Python 2.6.

Closes issue #3652.

Nick Coghlan d2e0938362 Issue #3781: Final cleanup of warnings.catch_warnings and its usage in the test suite. Closes issue w.r.t. 2.6 (R: Brett Cannon) 2008-09-11 12:11:06 +00:00
Brett Cannon 672237dc6c warnings.catch_warnings() now returns a list or None instead of the custom
WarningsRecorder object. This makes the API simpler to use as no special object
must be learned.

Closes issue 3781.

Brett Cannon 1eaf0742d8 Move test.test_support.catch_warning() to the warnings module, rename it
catch_warnings(), and clean up the API.

While expanding the test suite, a bug was found where a warning about the
'line' argument to showwarning() was not letting functions with '*args' go
without a warning.

Closes issue 3602.

Brett Cannon dea1b5653f warnings.warn_explicit() did not have the proper TypeErrors in place to prevent
bus errors or SystemError being raised. As a side effect of fixing this, a bad
DECREF that could be triggered when 'message' and 'category' were both None was
fixed.

Closes issue 3211. Thanks JP Calderone for the bug report.

Benjamin Peterson 2e6407d813 Practice EAFP, and revert 62787 2008-05-07 23:11:54 +00:00
Benjamin Peterson 323c40d48c Make the Python implementation of warnings compatible with the C implementation regarding non-callable showwarning 2008-05-06 22:31:52 +00:00
Brett Cannon 9c19bc6247 Remove the use of 'inspect' from 'warnings' for detected deprecated use of the
showwarning API. Turns out 'inspect' uses 'operator' which is an extension
module. That's a problem when it has not been built yet by setup.py.
2008-05-05 16:57:38 +00:00
Brett Cannon 8a232cc385 Add a DeprecationWarning for when warnings.showwarning() is set to a function
that lacks support for the new 'line' argument.
2008-05-05 05:32:07 +00:00
Brett Cannon e974689038 Re-implement the 'warnings' module in C. This allows for usage of the
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.

Closes issue #1631171.

Christian Heimes 28104c58d2 Expose Py_Py3kWarningFlag as sys.py3kwarning as discussed in #1504
Also added a warning.warnpy3k() as convenient method for Python 3.x related deprecation warnings.

Nick Coghlan b6983bbe15 Ignore ImportWarning by default 2006-07-06 13:35:27 +00:00
Brett Cannon 53ab5b761d 'warning's was improperly requiring that a command-line Warning category be
both a subclass of Warning and a subclass of types.ClassType.  The latter is no
longer true thanks to new-style exceptions.

Closes bug #1510580.  Thanks to AMK for the test.
2006-06-22 16:49:14 +00:00
Georg Brandl b2afe855e5 Make use of new str.startswith/endswith semantics.
Occurences in email and compiler were ignored due to backwards compat requirements.

Richard Jones 7b9558d37d Conversion of exceptions over from faked-up classes to new-style C types. 2006-05-27 12:29:24 +00:00
Phillip J. Eby 4703211080 Updated the warnings, linecache, inspect, traceback, site, and doctest modules
to work correctly with modules imported from zipfiles or via other PEP 302
__loader__ objects.  Tests and doc updates are included.
2006-04-11 01:07:43 +00:00
Brett Cannon bf36409e2a PEP 352 implementation. Creates a new base class, BaseException, which has an
added message attribute compared to the previous version of Exception.  It is
also a new-style class, making all exceptions now new-style.  KeyboardInterrupt
and SystemExit inherit from BaseException directly.  String exceptions now
raise DeprecationWarning.

Applies patch 1104669, and closes bugs 1012952 and 518846.

Tim Peters c885443479 Stop producing or using OverflowWarning. PEP 237 thought this would
happen in 2.3, but nobody noticed it still was getting generated (the
warning was disabled by default).  OverflowWarning and
PyExc_OverflowWarning should be removed for 2.5, and left notes all over
saying so.

Tim Peters 6602520473 SF bug 917108: warnings.py does not define _test().

Jeremy Hylton 8501466c7f Change warnings to avoid importing re module during startup.
Add API function simplefilter() that does not create or install
regular expressions to match message or module.  Extend the filters
data structure to store None as an alternative to re.compile("").

Move the _test() function to test_warnings and add some code to try
and avoid disturbing the global state of the warnings module.

Mark Hammond 51a0ae3f97 Ignore IOError exceptions when writing the message. 2002-09-11 13:22:35 +00:00
Walter Dörwald 65230a2de7 Remove uses of the string and types modules:
x in string.whitespace => x.isspace()
type(x) in types.StringTypes => isinstance(x, basestring)
isinstance(x, types.StringTypes) => isinstance(x, basestring)
type(x) is types.StringType => isinstance(x, str)
type(x) == types.StringType => isinstance(x, str)
string.split(x, ...) => x.split(...)
string.join(x, y) => y.join(x)
string.zfill(x, ...) => x.zfill(...)
string.count(x, ...) => x.count(...)
hasattr(types, "UnicodeType") => try: unicode except NameError:
type(x) != types.TupleTuple => not isinstance(x, tuple)
isinstance(x, types.TupleType) => isinstance(x, tuple)
type(x) is types.IntType => isinstance(x, int)

Do not mention the string module in the rlcompleter docstring.

This partially applies SF patch http://www.python.org/sf/562373
(with basestring instead of string). (It excludes the changes to
unittest.py and does not change the os.stat stuff.)

Raymond Hettinger 54f0222547 SF 563203. Replaced 'has_key()' with 'in'. 2002-06-01 14:18:47 +00:00
Neal Norwitz d68f5171eb As discussed on python-dev, add a mechanism to indicate features
that are in the process of deprecation (PendingDeprecationWarning).
Docs could be improved.

Tim Peters c86c1b88f9 resetwarnings(): change the docstring to reflect what the code
actually does.  Note that the description in the Library Reference
manual is already accurate.

Bugfix candidate.

Walter Dörwald b25c2b0a4a [Apply SF patch #504943]
This patch makes it possible to pass Warning instances as the first
argument to warnings.warn. In this case the category argument
will be ignored. The message text used will be str(warninginstance).
2002-03-21 10:38:40 +00:00
Guido van Rossum 8031bbec4a Allow for the possibility that globals['__name__'] does not exist;
substitute "<string>" for the module name in that case.  This actually
occurred when running test_descr.py with -Dwarn.
2001-08-31 17:46:35 +00:00
Guido van Rossum acc21d8814 Ignore OverflowWarning by default. To enable the warning, use
python -Wdefault

Skip Montanaro 40fc16059f final round of __all__ lists (I hope) - skipped urllib2 because Moshe may be
giving it a slight facelift

Guido van Rossum 3756fa3e11 Move a comment around to where it belongs (the code had alrady been
moved).
2001-02-28 22:26:36 +00:00
Guido van Rossum 9e26318975 Add a new API:
warn_explicit(message, category, filename, lineno, module, registry)

The regular warn() call calculates a bunch of values and calls
warn_explicit() with these.

This will be used to issue better syntax warnings.

Tim Peters e119006e7d Whitespace normalization. Top level of Lib now fixed-point for reindent.py! 2001-01-15 03:34:38 +00:00
Guido van Rossum 9464a7de60 - Added keyword argument 'append' to filterwarnings(); if true, this
appends to list of filters instead of inserting at the front.  This
  is useful to add a filter with a lower priority than -W options.

- Cosmetic improvements to a docstring and an error message.
2001-01-14 14:08:40 +00:00
Guido van Rossum d1db30b7b5 Improve error messages for invalid warning arguments; don't raise
